    Hi,

    My customer's device (TH940 / 4.1.4-GR1-P1) has the same issue.


    Apr 15 2019 01:55:56 Info    [SYSTEM]:Fan 3A is OK. Current value is 5640

    Apr 15 2019 01:43:58 Critical  [SYSTEM]:Fan 3A failed. Current value is 22080.


    TAC confirmed a HW RMA process at the time.

    But, personally I cannot completely rule out the possibility of SW bug on monitoring the fans because I experienced the bug of monitoring the fans on 2.7.1-GR1 & TH930 for 3 years. That was a bug at the time and We are a problem on the same fan!.

    I think it worth opening a case to investigate this.


    Regards,
